Increasing difficulty


If you stop and think about our app as it stands, it would be very easy to cheat! A user could just keep the ball very near the top edge and fling it a short distance to amass tons of points! If you'd like to make it harder for the user to score points, we will show you one way to increase the difficulty. If, on the other hand, you are making this app for a young user and want it to be easy for them to score points, then you can skip this section.
